MACHINE FOR FORGING SPIKES AND NAILS.

SPECIFICATION forming part of Letters Patent No. 540,36 1, dated June 4, 1895.

Applicationfiled June 23, 1 894- To all whom it may concern:

Be it known that I, J OHN S. Pnssnncnn, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented new and useful Improvements in Machines for Forging Spikes and the other Indicated Products in Metal, of which the following is a specification.

This invention relates to a machine for forging spikes, nails, bolts, rivets, pins, clips, staples, fish-plates and other like products in metal, and so constructed that more than one such product complete may be made in a single operation of the machine. Reference is made to the drawings hereto annexed as a part of this specification.

Figure 1 is a front elevation of the machine, so constructed as to yield two finished spikes or other such products in one complete operation. Fig. 2 is a left-side elevation of the same. Fig. 3 is a plan view of the same on the plane of about the top of the spikes seen in Fig. 1 Fig. 4 is a detached vertical section along the linesX and X respectively, of Fig. 1, showing the cutting and heading mechanisms with their associate gripping andquarter-turning mechanisms and section of griprods, grip-dies, and die-bed resting on the anvil-block 8. Fig. 5 is a front detached vertical section of the alternately cutting and heading mechanism worked, in a manner common in mechanics, by cams secured on the one revolving shaft. Fig. 6 is a front detached vertical section showing the rollers K K revolving the dies L L to seize and swage and deliver the stock W to the gripping-dies V of Fig. 4, these swaging-dies L L being of no greater width across their face than the width of the stock used. Fig. 6 shows, also, end sections of two parallel die-beds shown in Fig. 3, only one of which die-beds V appears in Fig. 4, which die-beds quarter-turn upward the two spikes as soon as sheared apart by the dies 1) b, Fig. 6, and hold the spikes vertically beneath the heading-dies it until headed and released. Fig. 7 is a front view of the swaging-dies L L completing a swaging of the stock W for two spikes, one of the two vertically-set lateral rollers M and its shaft appearing in dotted outline, which lateral rollers M M, shown in section in Fig. 3, prevent the spreading of the stock laterally Serial No. 515,549- (No model.)

while being swaged. Fig. 8 is a detached plan view of a die-bed V showing the top of the gripping-dies V open and set in and over the slot of the die-bed to movebackward and forward longitudinally on the quarter-turning die-bed resting on the anvil-block, Fig. 4, the dotted lines in Fig. 8 marking the removed grip-rods and the letter i indicating the spur-segments shown in transverse section,Fig. 9. Fig. 9 is an end view of-two parallel die-beds with spurs meshing in the spurs j of the rackj, Fig. 4, by which in the operation of the rack-segment P the heading mechanism quarter-turns and returns the die-beds opportunely.

In all the drawings each of the several parts of the machine is designated by one and the same letter'or figure.

Figs. 1, 2, and 3 show a vertical frame formed of two uprights A, A extending rearward to support the requisite revolving-shafts and gearing and cross-tied as indicated by the numbers 8. The top cross tie is looped rearward to allow the play of the top cams. two central cross ties 8 shown in Fig. 3, beginning on the plane W and extending downward are themselves cross-tied in the center a little below that plane so as to form the anvil-block, of which a section appears in Figs. 4 and 6 numbered 8, cored out to permil; the fall of the finished spikes.

In Fig. 1, I show the face of a pinion D terminating the driving-shaft, not shown, which crosses the frame showing its head 0 in Fig. 2; which driving-shaft O bears between the uprights A, A a fixed pulley marked B in Fig. 2 for the driving-belt and a loose pulley on which to shift the belt for stopping. This driving-pinion D meshes in the main gear-Wheel E secured on the shaft F bearing the fixed cams F to work the cutters and the fixed cam F to work the headers, and which shaft projecting through the upright A bears the gear-wheel F meshing in the gearwheels G and H as shown in Fig. 2.

Referring next to the plan Fig. 3 viewed with the lower section of Fig. 4, I show the gear-Wheels G and H secured respectively on the shafts G, H bearing respectively be tween the uprights A, A the cams G H which revolve between the rollers T, T, in a "manner common in mechanics, to thrust and The ilO

withdraw the grip'rods V, V carrying the dies V to grip the stock as received from the swaging-dies L, L, hold it under the cutters, turn in the die-beds with it for heading and releasing the finished product when complete, which may drop upon a conveying-belt stretched over the pulleys S, S Fig. 3. Immediately after the releasing of the finished product, the heading mechanism lifting the heading-dies engages the lugs 19 with the lugs n on the rack-segment P and thereby re turns the die-bed V for the next reception of the stock W from the swaging-dies L, L Fig. 6.

In the plan Fig. 3, I locate in the frame the die-bed V and its parallel duplicate, showing the spurs t' on the ends of each which mesh in the rack-spur j, Figs. 4 and 9, to quarter-turn the die-beds opportune'ly, the ends of the four grip-rods maintaining the grip-dies in their hold of the two spikes verticallyunder the heading-dies until complete. Corresponding ends of these parallel die-beds V appear in Fig. 6 in position of having just received the stock from the swaging-dies for shearing and immediately thereafter to quarter-turn upward with the severed spikes for their heading and release.

In Figs. 1 and 3, I show on the revolvingshaft H the pinion H meshing with the pinion H on the shaft H bearing the beveled pinion I meshing with the vertical beveled pinion I to revolve the shaft J on which is secured the roller K, Fig. 6; and on the other end of this shaft J is secured the gear-wheel J meshing with a pinion (not shown) secured to the shaft 0 to revolve the roller K, Fig. 6, opportunely.

As further details of the machine shown, although not restricted to particular details of well-known construction, I locate:

In Figs. 3 and 4 are shown the caps 5 and 6 and their duplicates in the rear which complete the bearings for the die-beds and griprods, and the clutches 7 which hold the quarter-turning grip-rods in the gripping mechanism operated by the cams G H also the cap 19 which secures the central shearing-die b of Fig. 6.

In Figs. 1 and 4, is shown the rod m which with its rear duplicate m are merely bearings for the rack-segments P.

In Figs. 1 and 5 are shown the caps r, 7" upon extensions inward of the frame A, A to form a loose rabbet-joint with the rabbets 0*, r of the heading die-gate as vertical bearings for this gate or block R. The pitmen cton which are hung the cross-bar a bearing the cutting die-rodsa, a 'fl are thrust and withdrawn by the cams F.

In Figs. 1, 2, 3 and 6, A is one of the twinuprights supporting between them the rollers K, K on the shafts J, O operated as hereinbefore described, and the lateral rollers M, M. The base-plate A of each of these uprights is shown in Fig. 1 to be adjustable to the baseplate A of the machine, and may be otherwise made adjustable to the frame A, so as to be set far or near according to the length of the product desired.

The dies L, L, Fig. 6, may be inserted in or form a part of the rollers K, K; and if swaging is not a requisite of the operation desired the lateral rollers M, M may be omitted and the face of the dies or seizing-surface of the rollers K, K may be wider than the width of the stock used.

In Fig. 1,I locate in the frame the front vertical rack j with the end view of the plate T which carries the roller T of the gripping mechanisms, this rack and plate appearing in vertical section in Fig. 4, a plan view of this plate T appearing in Fig. 3.

It is to be noted that the three gear-wheels F, G and H are of like diameter, and the pinions H and H are of like diameter; also beveled pinions I and I are of like diameter; and the gear-wheel J and the duplicate above it on the shaft 0 are of like diameter. With the several gear-wheels and pinions thus mutually related and the cams F and F and the grippingcams G H 3 ustly related, the operation of the machine will be timed for the following five consecutive motions duly, namely: first, seizing, swaging and delivering the stock to the gripping-dies; second, gripping the stock thus delivered; third, thrusting the cutting-dies to shear the stock in two; fourth, quarter-turning the die-beds containing the gripped and severed stock to be held under the heading-dies; fifth,thrusting the heading-dies to finish the product complete. At this point the repetition of these five motions begins, the grip-rods are withdrawn to release the finished product followed by returning the die beds back to position for next receiving and gripping more stock.

Having thus described my invention, what I claim, and desire to secure Letters Patent for, is

1. The combination, with the revoluble s'waging dies L L, the two pivoted pairs of separable gripping dies V the two vertically reciprocating heading dies h arranged over the gripping dies, and the two vertically reciprocating cutters b arranged respectively in front of and between the said heading dies; of driving mechanism operating the said dies and cutters, substantially as set forth.
